Answer:
Commutative Property of Addition: a + b = b + a
Step-by-step explanation:
The Commutative Property of Addition implies that even on changing the order of addition the final result (i.e. the sum) remains the same.
- Consider the addition of two numbers, say <em>a</em> and <em>b</em>:
a + b = b + a
Suppose <em>a</em> = 5 and <em>b</em> = 6, then:
<em>a</em> + <em>b</em> = 5 + 6 = 11
<em>b</em> + <em>a</em> = 6 + 5 = 11.
Thus, a + b = b + a.
- Consider the addition of three numbers, say <em>a, b</em> and <em>c</em>:
a + b + c= a + c + b = b + a + c = c + a + b
Suppose <em>a</em> = 4, <em>b</em> = 3 and <em>c</em> = 6, then:
a + b + c = 4 + 3 + 6 = 13
a + c + b = 4 + 6 + 3 = 13
b + a + c = 3 + 4 + 6 = 13
c + a + b = 6 + 4 + 3 = 13.
Thus, a + b + c= a + c + b = b + a + c = c + a + b.
Answer:
Chukwu's share is of $57.
Step-by-step explanation:
This question is solved by a system of equations.
I am going to say that:
Chukwu's share is x.
Abdul's share is y.
Kunle's share is z.
Chukwu, Abdul and kunle are to share $142
This means that 
Abdul gets $11.00 less than Chukwu
This means that:
$7.00 more than Kunle.
This means that:
So
How much is Chukwu's share?
We want to find x, so:
Chukwu's share is of $57.
A) is 2.5 x 10^4
B) is 8.1 x 10^3
C) is 90.6 x 10^6
D) is 10.34 x 10^7
Sorry if I’m wrong, x
We need to find how many students have at least one social media account.
We know that there are 120 students in the class.
We also know that there are 65% of students that have at least one social media account.
To find your answer, would multiply 120 by 0.65:
120 · 0.65 = 78
This means that 78 of the students has at least one social media account.
Answer:
78 students
9514 1404 393
Answer:
m = (5x -6)/(43y -4)
Step-by-step explanation:
Subtract 4m+6 to separate m-terms from other terms.
5x +4m -(4m +6) = 43my +6 -(4m +6)
5x -6 = 43my -4m
5x -6 = m(43y -4) . . . . factor out m
(5x -6)/(43y -4) = m . . . . divide by the coefficient of m
